Abstract
Description
Technical Field
[0001] The invention relates to the technical field of oil production engineering, in particular to a portable high-dispersion constant-temperature dissolving device. Background Art
[0002] The dissolution process for high-molecular materials, such as polymers, requires a certain amount of time and temperature. This is because their long molecular chains require sufficient energy to fully decompose. This leads to problems with traditional dissolution apparatuses when handling these materials. Currently, commonly used dissolution apparatuses in laboratories primarily consist of a beaker and a magnetic stirrer. While this magnetic stirring method can facilitate dissolution to a certain extent, it can easily lead to a decrease in stirring speed or "loss of rotation" as the viscosity of the solution increases. This means that as the dissolution process progresses, the polymer dissolution rate is affected, which in turn affects the final dissolution result. During the addition process, excessive addition can easily lead to the formation of difficult-to-dissolve "clumps" and "fish-eye" particles. These particles affect the polymer's dissolution rate and dissolution quality, making the entire dissolution process more complex and time-consuming. Laboratory dissolution apparatuses are typically fixed, making them inconvenient to move to the field. However, in certain application scenarios, such as construction sites or field sampling sites, the ability to quickly and conveniently dissolve high-molecular materials is crucial. Therefore, this fixed dissolution apparatus has limited its application in these scenarios. Maintaining constant temperature during the dissolution process is also crucial. This is because temperature fluctuations can affect the polymer dissolution rate and the final dissolution effect. However, existing dissolution equipment struggles to maintain constant temperature conditions both on-site and indoors, resulting in inconsistent dissolution results under different environments. This inconsistency can impact subsequent applications and research. Summary of the Invention

The purpose is only to facilitate the description of the present invention and simplify the description. It does not indicate or imply that the referred parts must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.
[0017] like Figure 1-2 As shown, the present invention provides a portable high-dispersion constant temperature dissolution device, comprising: a sealing cover 1, a dissolution cup 9, a heating base 10 and a power base 11; The dissolving cup 9 is a hollow cylindrical structure. A sealing cover 1 is provided at the upper end of the dissolving cup 9, a heating base 10 is provided at the lower end of the dissolving cup 9, and a power base 11 is provided at the lower end of the heating base 10. The size of the heating base 10 is the same as that of the lower end of the dissolving cup 9. The sealing cover 1 is provided with three through holes at the upper end, namely a first through hole, a second through hole and a third through hole. A feeding funnel 2 is provided in the first through hole, an electric stirrer 3 is provided in the second through hole, and a temperature probe 4 is provided in the third through hole. The electric stirrer 3 is driven by a motor 5, which is provided at the upper end of the second through hole and connected to the electric stirrer 3 at the lower end of the motor 5. A controller 7 is provided on the third through hole, and the lower end of the controller 7 is connected to the temperature probe 4. A switch 12 and a setting disk 13 are provided at the upper end of the controller 7. A coupler 8 is provided on one side of the dissolving cup 9, which is used to connect the dissolving cup 9 and the sealing cover 1 to ensure the seal between the two. The upper end of the sealing cover 1 is provided with a groove, the size of which matches the size of the battery 6, so that the battery 6 can be fit into it; A feeding funnel 2 is provided in the first through hole, and a spring cover device is provided at the lower end of the feeding funnel 2. The spring cover device controls the sealing state of the dissolving cup 9. The feeding funnel 2 has a double-layer structure. The top radius of the upper funnel of the feeding funnel 2 is larger than the top radius of the lower funnel. The bottom of the upper funnel is embedded in the top of the lower funnel, so that the medicine enters the dissolving cup 9 more evenly during the process of entering the dissolving cup 9 from the feeding funnel 2. The funnel wall of the feeding funnel 2 is provided with a vibration mechanism 14. The vibration mechanism 14 is spirally embedded in the funnel wall of the feeding funnel 2. The vibration mechanism 14 can vibrate intermittently. The vibration mechanism 14 allows the medicine to enter the dissolving cup 9 from the feeding funnel 2 in a dispersed manner, thereby avoiding concentrated accumulation of medicine and improving dissolution efficiency and effect.
[0018] The controller 7 is provided with a switch 12 and a setting dial 13. The switch 12 is used to control the power on / off state of the heating base 10, the electric stirrer 3, and the vibration mechanism 14. The setting dial 13 is used to adjust the temperature of the heating base 10 and the stirring speed and stirring time of the electric stirrer 3. Through the setting dial 13, the user can adjust the temperature, speed, and time according to the characteristics of the drug and the dissolution requirements to achieve the best dissolution effect. The heating base 10 and the temperature probe 4 constitute the constant temperature device of the portable high-dispersion constant temperature dissolution device. This constant temperature device can ensure that the device performs the dissolution and stirring operation on the drug at the set temperature state. The temperature probe 4 can monitor the temperature in the dissolution cup 9 in real time and transmit the data to the controller 7. The controller 7 adjusts the heating power of the heating base 10 based on this data to keep the temperature in the dissolution cup 9 stable at the set value. This design allows the drug to maintain a constant temperature during the dissolution process, improving the dissolution effect and safety.
[0019] The material of the electric stirrer 3 is polytetrafluoroethylene, which is a synthetic polymer with excellent performance. Polytetrafluoroethylene has the characteristics of high temperature resistance, corrosion resistance, high lubrication, low temperature resistance and aging resistance. Selecting polytetrafluoroethylene as the material of the electric stirrer 3 is beneficial to protecting the chemical properties of the polymer and at the same time making the service life of the electric stirrer 3 longer. The blades at the lower end of the electric stirrer 3 are cylindrical structures. Usually, the number of blades is 4. The 4 cylindrical blades are evenly arranged at the bottom of the rotating rod of the electric stirrer 3 to ensure uniformity and stability during the stirring process. The cylindrical blades prevent the polymer molecular chains of the electric stirrer 3 from breaking during the stirring process. This is because the cylindrical blades can effectively disperse the shear force generated by stirring, avoiding the damage to the polymer molecular chains caused by local stress concentration.
[0020] The battery 6 provided at the upper end of the sealing cover 1 can provide the electric energy required for the operation of the electric stirrer 3, the heating base 10, and the vibration mechanism 14. This allows the portable high-dispersion constant-temperature dissolution device to continue to operate even without an external power supply. The user can carry it to a work site without power supply equipment. The battery 6 improves the portability and applicability of the portable high-dispersion constant-temperature dissolution device. In actual use, it is only necessary to ensure that the battery 6 is fully charged to perform the dissolution operation at a work site without power supply equipment. This allows the device to cope with various emergencies and complex environments, providing great convenience for the user.
[0021] The following is a detailed introduction to the actual working scenario of the portable high-dispersion constant temperature dissolution device.
[0022] When conducting a dissolution experiment in the laboratory, first connect the power base 11 to the power supply to ensure the normal operation of the device, turn on the switch 12 on the top of the controller 7, so that the heating base 10, the electric stirrer and the vibration mechanism 14 are connected to the power supply, and prepare for the dissolution experiment. By adjusting the setting disk 13 on the top of the controller 7, the dissolution temperature, dissolution speed and stirring time of the electric stirrer 3 of the device are set. In actual operation, these parameters can be adjusted according to the characteristics of the drug and experimental requirements to achieve the best dissolution effect. Observe the reading of the temperature probe 4. When the temperature reaches the temperature required for dissolution, add the material through the feeding funnel and start the dissolution experiment. After the addition is completed, the polymer begins to dissolve under the set temperature and stirring. In this process, the electric stirrer 3 will stir according to the set speed and time to make the dissolution more sufficient and uniform. After the dissolution is completed, the polymer is completely dissolved. At this time, the switch 12 can be turned off to stop heating and stirring to complete the dissolution.
[0023] When conducting a dissolution experiment at the work site, since there is no external power supply available, it is necessary to fully charge the battery 6 in advance, turn on the switch 12 on the top of the controller 7, and connect the power to the heating base 10, the electric stirrer, and the vibration mechanism 14 to prepare for the dissolution experiment. By adjusting the setting disk 13 on the top of the controller 7 to set the dissolution temperature, dissolution speed, and stirring time of the electric stirrer 3, in actual operation, these parameters can be adjusted according to the characteristics of the drug and experimental requirements to achieve the best dissolution effect. Observe the reading of the temperature probe 4. When the temperature reaches the temperature required for dissolution, add the material through the feeding funnel and start the dissolution experiment. After the addition is completed, the polymer begins to dissolve under the set temperature and stirring. During this process, the electric stirrer 3 will stir according to the set speed and time to make the dissolution more sufficient and uniform. After the dissolution is completed, the polymer is completely dissolved. At this time, the switch 12 can be turned off to stop heating and stirring to complete the dissolution work.
